  • THE CARBON DIOXIDE LEAKAGE FROM CHAMBERS

    Dec 22, 2005In plant chamber studies, if Co2 leaking from a chamber is not quantified, it can lead to an overestimate of assimilation rates and an underestimate of respiration rates: consequently, it is critical that Co2 leakage be determined. Sulfur Hexafluoride (SF6) was introduced into the chambers as a tracer gas to estimate leakage rates. Chamber leakage in the chambers occurs via pressure
